How to buy a vibrator at 19?

I want to buy a vibrator. I’m almost 19. I live with my parents and would probably only use it when no one is home. I can’t order anything online in fear of it arriving and someone opening it. I was thinking of going into cvs although I’m shy to go out and buy somthing it’s probably the only way. Spencer’s products I’ve seen mixed reviews. Does CVS card? I live in Oregon.
